Ingredients Overview

Each component in this recipe plays a key role in creating that signature fudgy-meets-chewy texture.

For the Brownie Layer

• Butter: Provides richness and a glossy finish. Melting it with chocolate ensures a smooth, fudgy base.

• Chocolate: Use good-quality dark or semi-sweet chocolate (70% cocoa is ideal) for depth and intensity.

• Sugar: A mix of white and brown sugar gives chewiness and a slightly caramelized note.

• Eggs: They create structure and that signature shiny brownie top.

• Flour: Just enough to bind — too much flour and your brownies become cakey instead of fudgy.

• Cocoa Powder: Deepens the chocolate flavor for an indulgent bite.

• Salt & Vanilla: Balance sweetness and enhance the overall flavor.

For the Cookie Layer

• Butter: Softened (not melted) butter ensures a light, chewy cookie texture.

• Sugar: Both brown and white sugars contribute moisture and sweetness.

• Egg: Binds the dough and adds tenderness.

• Flour & Baking Soda: Provide structure and help the cookie layer puff slightly.

• Chocolate Chips: Use semi-sweet or milk chocolate chips for classic cookie flavor and melty pools of chocolate.

Step-by-Step Instructions

Step 1: Preheat and Prepare the Pan

Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving a bit of overhang for easy removal later.

Step 2: Make the Brownie Batter

1. In a microwave-safe bowl, melt ½ cup (1 stick) butter with 4 oz chopped dark chocolate in 30-second bursts, stirring until smooth.

2. Whisk in ¾ cup sugar and ¼ cup brown sugar until glossy.

3. Add 2 large eggs and 1 teaspoon vanilla extract, whisking until combined.

4. Sift in ½ cup all-purpose flour, ¼ cup cocoa powder, and ¼ teaspoon salt.

5. Gently fold until just combined — don’t overmix. The batter should be thick and shiny.

6. Pour the brownie batter into the prepared pan and smooth the top.

Step 3: Make the Cookie Dough

1. In another bowl, cream together ½ cup (1 stick) softened butter, ½ cup brown sugar, and ¼ cup granulated sugar until light and fluffy.

2. Mix in 1 large egg and 1 teaspoon vanilla extract.

3. Add 1¼ cups all-purpose flour, ½ teaspoon baking soda, and ¼ teaspoon salt.

4. Fold in ¾ cup chocolate chips.

Step 4: Assemble the Brookies

Drop spoonfuls of cookie dough over the brownie batter. Gently spread or press the dough to cover most of the surface, leaving a few chocolatey patches exposed. (Don’t overmix layers — you want that marbled effect!)

Step 5: Bake

Bake for 28–32 minutes, until the top is golden and a toothpick inserted in the center comes out with a few moist crumbs.

Tip: For extra fudgy brookies, slightly underbake them — they’ll continue to set as they cool.

Step 6: Cool and Slice

Cool completely in the pan before slicing. For clean cuts, chill the brookies for 30 minutes, then use a sharp knife to cut into squares.

Tips, Variations, and Substitutions

• Extra Gooey: Add a few chocolate chunks on top before baking for melted puddles of chocolate.

• Salted Finish: Sprinkle with flaky sea salt right after baking for a gourmet touch.

• Nutty Twist: Add chopped walnuts or pecans for crunch.

• Peanut Butter Swirl: Drizzle warm peanut butter over the brownie batter before adding cookie dough.

• Espresso Boost: Stir 1 teaspoon espresso powder into the brownie batter to deepen chocolate flavor.

• Caramel Drizzle: Once cooled, drizzle with caramel sauce for a sweet-salty combo.

• Gluten-Free: Substitute flour with a 1:1 gluten-free blend — the texture remains chewy and fudgy.

Nutritional & Health Notes

Each brookie (based on 9 large squares) contains approximately 320–360 calories, depending on chocolate type.

Nutrition Highlights:

• Rich in antioxidants: Dark chocolate contains flavonoids that support heart health.

• Mood booster: Cocoa and sugar release serotonin for that “feel-good” dessert satisfaction.

• Energy source: Carbs and fats make this the perfect indulgent pick-me-up.

To lighten up the recipe, use half the sugar or swap half the butter for unsweetened applesauce — though, let’s be honest, this dessert is meant to be decadently rich!
